LIQUID-FUEL BURNER.

Specification of Letters Patent.

- Patented Nov. 26, 1907.

Application filed January 4-, 1907. Serial No. 350712.

To all whom it may concern:

Be it known that 1, JOHN H. Kooxs, a citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have invented a new and 1m roved Liquid-Fuel Burner, of which the foll dwing is a full, clear, and exact description.

Thisinvention relates to improvements in burners for gas produced by the adnnxturc of oil or denaturized alcohol, with low pres:- sure air and high pressure air or steam, the object being to provide a burner with which an intense heat may be obtained ,and particularly adapted for use in connection with mill- 1 will describe a gas burner embodying my invention, and then point out the novel features-in the appended claim.

Reference is to behad to the accompanyving drawing forming a part of this specification, and to the characters of reference marked thereon.

The figure of the drawing is a longitudinal section of a gas burner embodying my invention.

The burner comprises a tubular casing or pipe 1 for receiving air at atmospheric or low pressure from a. lpe 2, and this air-inlet is controlled by a s de valve 3. The casing or pipe 1 is reducedat its end, forming a mixing chamber 4, surrounding which is a Water jacket 5 having an inlet-pipe 6 and an outletpipe 7.

The circulation of Water around the outlet of the burner or mixing chamber will prevent the burning out of the device.

Extended through the casing or pipe 1 is a tube for the passage of air under high pres sure, or for the passage of steam, as may be desired. This tube 8 has a restricted outlet 9, and is supplied with the high-pressure medium through a pipe 10.

Arran ed within the tube 8 is an oil or alcohol supp y pipe or tube 11, having a nozzle tube 12 provided with a restricted outlet 13, the said outlet being regulated by a valve 14:, the stem 15 of which 1s projected out-ward through the end of said pipe or tube 11 and proyided with a haudpiece 16. The valve 14 is provided with an annular spirally-dis posed channel 17, which will cause a spiral action of the oil or alcohol passing through the tube so that the oil or alcohol will thoroughly mix with the air or steam.

The oil or alcohol is admitted to the pipe 11 through a pipe 18, and below this pipe l.\' a nipple 1!) provided with a valve 20, and through this nipple 1!) oil or alcohol may be discharged to test its quality or density.

In operation, the oil or alcohol discharged through the opening 13 will be thoroughly mixed with the low-pressure air and the highpressure air or steam. and when ignited will produce an intense flame.

Having thus described my invention '1 claim as new and desire to secure by Letters Patent A burner of the character described, comprising a tubular casing having one end reduced to form a mixing chamber and provided with a water jacket sinirounding the same, the other end of the casing having a lateral valved low pressure air inlet, a high ressure pipe secured in the casing and hay.- lng its inner end apertured and arranged adjacentto the reduced end of theorising, the

other end of the pipe extending out through the end of the casing opposite its reduced end and having a lateral inlet, a liquid fuel pipe secured in the high pressure pipe and extending out through the outer end of the same and having a lateral inlet, a nozzle on the in ner end of the fuel pipe, said nozzle being adjacent to'the aperture of the high pressure pipe, and a spirally grooved valve in the nozzle and having its stem extending out through said fuel pipe.

In testimony whereof'I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN H. KOOXS.
